Struct mz_repr::adt::date::Date

source ·
pub struct Date { /* private fields */ }
Expand description

A Postgres-compatible Date. Additionally clamp valid dates for the range that chrono supports to allow for safe string operations. Infinite dates are not yet supported.

Implementations§

source§

impl Date

source

pub const UNIX_EPOCH_TO_PG_EPOCH: i32 = 10_957i32

source

pub const LOW_DAYS: i32 = -2_451_545i32

source

pub const HIGH_DAYS: i32 = 95_015_279i32

Largest date support by Materialize. Although Postgres can go up to 5874897-12-31, chrono is limited to December 31, 262142, which we mirror here so we can use chrono’s formatting methods and have guaranteed safe conversions.

source

pub fn from_pg_epoch(days: i32) -> Result<Date, DateError>

Constructs a new Date as the days since the postgres epoch (2000-01-01).

source

pub fn from_unix_epoch(unix_days: i32) -> Result<Date, DateError>

Constructs a new Date as the days since the Unix epoch.

source

pub fn pg_epoch_days(&self) -> i32

Returns the number of days since the postgres epoch.

source

pub fn is_finite(&self) -> bool

Returns whether this is the infinity or -infinity date.

Currently we do not support these, so this function is a light protection against if they are added for functions that will produce incorrect results for these values.

source

pub fn unix_epoch_days(&self) -> i32

Returns the number of days since the Unix epoch.

source

pub fn checked_add(self, days: i32) -> Result<Date, DateError>

Returns this date with days added to it.
